Abstract
A printed circuit board (PCB) capable of withstanding ultra high G forces and ultra high temperature as in a gas turbine (). The PCB includes a substrate having a plurality of cavities (A,A) formed therein for receiving components of a circuit, and conductors embedded in the PCB for electrically connecting the components together to complete the circuit. Each of the cavities has a wall (A') upstream of the G-forces which supports the respective component in direct contact in order to prevent the development of tensile loads in a bonding layer (A). When the component is an integrated circuit (), titanium conductors () are coupled between exposed ends of the embedded conductors and contact pads on the integrated circuit. A gold paste () may be inserted into interstitial gaps between the integrated circuit and the upstream wall.
